I need to animate graphics over a large.jpg set as the forms background.

Reloading the image each time the animation moves is not an option as it 
takes too long.

I thought drawing on a transparent panel would be the answer indeed it works 
with a non transparent panel but not with a transparent one.

The drawing code uses CreateGraphics in the mousemove event.  With a the 
background color set to transparent the event isn't even triggered !?

Also if i use graphics.clear(color.transparent) then panel turns black
 
Any ideas ?

Read the GDI+ FAQ on:
